The present invention relates to a home automation system, and more particularly, to a data transmission and reception apparatus of a home automation system.

Generally, home appliances that are widely used in home automation systems in general households include TVs, refrigerators, washing machines, microwave ovens, air conditioners, etc., each of which has a corresponding control unit or an operation unit installed in the product body. The remote controller controls the operation of the home appliance or controls its operation by operating its own control unit.

As described above, each of the conventional home appliances includes a corresponding remote control. As the number of home appliances operated by the remote control increases, the remote control increases, and the storage and management of the increased remote control becomes difficult. Controlling home appliances is cumbersome, and since each home appliance is individually controlled, integration and optimization are not possible.

In order to solve this problem, it was difficult to execute each product because it lacked the function of the microcomputer and the memory capacity of each product in order to remotely control a protocol such as TCP (transfer control protocol / IP). .

Accordingly, an object of the present invention is to provide a data transmission / reception apparatus of a home automation system, which allows a plurality of home appliances to be simultaneously connected to one PC through a single adapter.

Inverts the second transistor which blocks the flow of the signal to the second microcomputer when the control signal is input to the base and is driven to output the signal from the first transistor, and inverts the signal output from the first transistor or the second transistor, It is configured to include an adapter for converting to a predetermined voltage level for communication and transmitting to the PC through the transmitter It has its features.

Hereinafter, a data transmission and reception apparatus of a home automation system according to the present invention will be described with reference to the accompanying drawings.

1 is a block diagram showing the configuration of a data transmission and reception apparatus of a home automation system according to the present invention.

As shown in FIG. 1, the data transmission / reception apparatus of the home automation system according to the present invention bi-directionally with each home appliance by simultaneously connecting the first through Nth home appliances having the first through Nth microcomputers to one PC. and in the data transmitting and receiving device of the home automation system communication is possible, the first microcomputer first transistor (Q ₁₁₀₎ in the base is connected to a 310 base-powered whether the determination as a predetermined signal input, wherein the first agent transistor (Q _110), depending on whether the drive is driven by receiving a control signal of the second microcomputer 410 to the base of the first corresponding to the transistor (Q _110), the signal output during the second microcomputer 410 from a signal of a a second transistor (Q ₁₂₀₎ to block the flow, wherein the first transistor (Q ₁₁₀₎ or the second transistor (Q ₁₂₀₎ a predetermined voltage to the communication with an inverting and a signal output from the PC (100) on the rail Conversion is configured to include an adapter 200 for transmission to the PC (100) through the transmitter to.

Here, the adapter 200 is output from the third transistor Q ₁₃₀ and whether the driving is determined as a signal having a predetermined level is input to the base, and is output from the first transistor Q ₁₁₀ or the second transistor Q ₁₂₀ . A first resistor R ₁₁₀ for applying a divided signal to divide the level of the corresponding signal to apply a divided level signal to the base of the third transistor Q ₁₃₀ or to apply a 0 V level signal; And a communication port 210 for receiving and outputting the signal output from the third transistor Q ₁₃₀ to the receiving terminal R _X120 and converting the signal to a predetermined voltage level for communication with the PC 100. .

At this time, the communication port 210 is characterized in that the RS-232 communication chip.

In addition, fourth and fifth transistors Q ₁₄₀ and Q ₁₅₀ are connected to receiving terminals R _X130 and R _{X140 of} the first and second microcomputers 310 and 410, respectively, and the adapter 200 The sixth transistor Q ₁₆₀ is also connected to the communication port 210 of the communication port T _X120 .

Referring to the operation of the data transmission and reception apparatus of the home automation system according to the present invention configured as described above are as follows.

First, the microcomputer 310 in the first home appliance 300, that is, the first microcomputer 310 receives and analyzes a signal transmitted from the PC 100 to the receiver R _X130 through the adapter 200 and analyzes it. If the received signal is an operation command signal for the first household appliance 300, the first household appliance 300 is controlled to operate according to the corresponding signal.

The first microcomputer 310 transmits a completion signal through the transmitter T _X130 when the first home appliance 300 is normally operated.

That is, for example, when the first microcomputer 310 transmits a 'high' signal through the transmitter T _X130 , the transmitted 'high' signal is input to the base of the first transistor Q ₁₁₀ .

Subsequently, the first transistor Q ₁₁₀ is turned on as the 'high' signal is input to the base to generate a predetermined signal to the collector terminal.

At this time, the signal generated at the collector terminal of the first transistor Q ₁₁₀ is transmitted to the base of the third transistor Q ₁₃₀ in the adapter 200.

Here, when the first home appliance 300 is in communication with the PC 100, the second home appliance 400 does not communicate with the PC 100.

In this case, since the second home appliance 400 is not in communication, the second transistor Q ₁₂₀ connected to the microcomputer 410, that is, the second microcomputer 410 transmitting terminal T _{X140 in} the second home appliance 400. Is turned off.

As a result, since the second transistor Q ₁₂₀ of the second household appliance 400 is turned off when the first household appliance 300 is in communication, the first transistor Q of the first household appliance 300 is turned off. _The signal transmitted from the ₁₁₀ to the adapter 200 is input to the base of the third transistor Q ₁₃₀ of the corresponding adapter 200 without attenuation.

In this case, the signal input to the base of the third transistor Q ₁₃₀ is divided into a signal of a predetermined level by the first resistor R ₁₁₀ , and the divided signal of the predetermined level is applied to the base.

Subsequently, the third transistor Q ₁₃₀ is turned on as a predetermined signal is input to the base, and transmits a 'low' signal to the communication port, that is, the receiving terminal R _X120 of the RS-232 communication chip 210.

The communication port 210 converts the signal into a predetermined voltage level while inverting the 'low' signal transmitted from the third transistor Q ₁₃₀ and transmits the signal to the PC 100 through the transmission terminal T _X110 . do.

Here, the communication port 210 receives a signal transmitted from a plurality of home appliances for communication with the PC 100 and converts it into a signal of -10V to + 10V level.                     

As a result, the PC 100 receives the 'high' signal transmitted from the first microcomputer 310 without attenuation.

In addition, when the first microcomputer 310 transmits a 'low' signal through the transmitting terminal T _X130 , the first transistor Q ₁₁₀ is turned off by receiving the transmitted signal as a base.

Subsequently, since the signal is not input to the third transistor Q _{130 in} the adapter 200 through the collector terminal of the first transistor Q ₁₁₀ as a base, the third transistor Q ₁₃₀ has a 0 V level through the first resistor R ₁₁₀ . It is turned off by receiving a signal.

In this case, the third transistor Q ₁₃₀ outputs a 'high' signal to the receiving terminal R _X120 of the communication port 210.

Subsequently, the communication port 210 converts the signal into a predetermined voltage level while inverting the 'high' signal input through the receiving terminal R _X120 and transmits the signal to the PC 100 through the transmitting terminal T _X110 .

As a result, the PC 100 receives the 'low' signal transmitted from the first microcomputer 310 without attenuation from the signal input through the receiver R _X100 .

Similarly, when the second microcomputer 410 transmits a 'high / low' signal to the PC 100 through the second transistor Q ₁₂₀ , the first microcomputer 310 transmits a predetermined signal. Since the operation is the same as the method, when the predetermined signal is transmitted from the second microcomputer 410 to the PC 100, the signal is transmitted to the PC 100 without attenuation of the signal.

That is, when a predetermined signal is transmitted from the second transistor Q ₁₂₀ to the adapter 200, the first microcomputer 310 does not communicate with the PC 100. ₁₁₀ is turned off to block the signal output from the second transistor Q ₁₂₀ to be transmitted to the first microcomputer 310.

As a result, a signal transmitted from the second microcomputer 410 is also transmitted to the PC (00) without attenuation, and the PC (100) does not attenuate a predetermined signal transmitted from a plurality of home appliances connected at the same time, that is, a signal damage. Will be sent without

As described above, the data transmitting / receiving apparatus of the home automation system according to the present invention receives an undamaged signal transmitted from a plurality of home appliances connected to one PC at the same time through a single adapter, and the corresponding PC receives a plurality of signals. Efficient control and monitoring of home appliances can provide users with the convenience of using home appliances in their homes.
